Question

I need to make a loop that runs for 3 times and a switch for three age groups 0-10 11-20 and 21-65 with the following code:

class Program
    {
        private static object N;
        static void Main(string[] args)
        {
            string answer;                                   
            {
              Console.WriteLine("please enter your name:");
              string name = Console.ReadLine();

              Console.WriteLine("please enter your surname:");
              string surname = Console.ReadLine();

              Console.WriteLine("please enter your age:");
              string age = Console.ReadLine();        

              Console.WriteLine("please enter your adress:");
              string adress = Console.ReadLine();

              Console.WriteLine("hallo,{0} {1},veel sucess met C#", name, surname);

              Console.WriteLine("zijn deze gegevens juist? J/N");
              answer = Console.ReadLine();
            }
            while(answer == "N");
        }
   }      

I tried some things to test the age, but I always got errors. Also, I don’t know how to write the loop code correctly.

Can somebody please point me in the right direction for both problems?

Sorry for my bad English I’m Dutch.

NOTE: the OP mentioned under one of the answers that this is not a homework assignment.

Answer 1

Switch statements operate on specific values, not ranges, so you’d want to use a series if statements instead.

Use a counter (declared outside of the loop and incremented on every execution) to determine how many times the loop has run (or use a for loop).

Edit

class Program
{
    private static object N;

    static void Main(string[] args)
    {
        string answer;
        int runCount= 0;

        do
        {
          ++runCount;
          Console.WriteLine("please enter your name:");
          string name = Console.ReadLine();

          Console.WriteLine("please enter your surname:");
          string surname = Console.ReadLine();

          Console.WriteLine("please enter your age:");
          int age = int.Parse(Console.ReadLine());

          if(age >= 0 && age <= 10)
          {
              Console.WriteLine("Child");
          }
          else if(age <= 20)
          {
              Console.WriteLine("Young adult");
          }
          else if(age <= 65)
          {
              Console.WriteLine("Adult");
          }

          Console.WriteLine("please enter your adress:");
          string adress = Console.ReadLine();

          Console.WriteLine("hallo,{0} {1},veel sucess met C#", name, surname);

          Console.WriteLine("zijn deze gegevens juist? J/N");
          answer = Console.ReadLine();
        }
        while(runCount < 3 && answer == "N");
    }
}
